900 SERIES PINTLE CHAINS, sometimes referred to as “sugar mill” or “intermediate carrier chain” is utilized extensively in sugar mills. Multiple strands of 900 Pintle Chain, available with one or two holes per link, could be installed with overlapping beaded carrier slats to create a continuous apron conveyor for intermediate carrier support.
The pin holes at the closed end of the 900 Class link are given with smooth bushings which are press-fitted in to the links and keyed into place. The bushings are renewable and can be driven out and replaced if they become worn. 900 Class Pintle Chain is designed with dual barrels, one on each part of the open end of the links, to accommodate double sprockets. The objective of this driving method is to eliminate the possibility of material build-up in the sprocket contact area, which frequently causes the chain to leap the sprocket. Large ribs rigidly reinforce these traveling barrels.
Our 900 Course chain links, with tensile power from 22,500 to 32,500 pounds, can be found with large sliding surfaces to reduce chain wear and prolong chain lifestyle. Broad wearing surfaces and large cross sections synergy to provide a substantial link which is manufactured according to manufacturer’s criteria and can perfectly replace links created by other manufacturers.
Brutaloy sprockets for 900 Class Pintle Chain are plentiful in 3.170 inches. 900 Class Pintle Chain should only be allowed to travel in one direction; links should run in the direction of their shut narrow end.
Obtainable in cottered construction only, 900 Class Chain is definitely assembled with T-headed pins which are locked into place by two lugs cast upon the ends of the driving barrels to avoid pin rotation. Pin rotation during operation would lead to wear within the bushing. Both the mind of the pin and the cottered end of the pin are protected by cast lugs on the barrel 
end of the links.
Material
900 Class Pintle Chain are links cast of malleable iron or Promal (Duramal). It Drive Chain really is furnished with carbon steel heat treated pins and carbon metal case hardened bushings as standard. However, stainless pins and bushings can be provided when specified.
